SORRY, But it don't have a timing belt. It has timing chain and gears.
The timing on that engine is controled by the PCM / computer. You can set it by ear good enough to make it run. But you will need a OBD II engine scanner to get it right.There is no other way.
There are a few ways to set the timing on a 1994 Suburban 1500. Disconnect the connector firewall to loosen the distributor turning just a bit clockwise.
To set the timing on a 1994 GMC Suburban you need to warm up the engine while the car is either in park or neutral. Next, you adjust the distributor until the timing is set to where you want it.
If the distributor has not been moved the timing will be as it was before.
ignition timing is electronic. follow the procedure in the repair manual for installing the distributor. Jeep does not have a base timing position.
That requires an OBDII engine scanner to do that. The ignition timing is controlled by the computor. If you have not moved are removed the distributor then there's no reason to fool with the timing.
Yes the rotor should be pointing to the #1 cylinder when you are installing the distributor.
Bring No1 piston to TDC on the compression stroke. Look at the rotor to make sure its pointing to the No1 plug tower. If it is remove the distributor. THEN DON'T MOVE THE ENGINE. When installing distributor make sure the rotor is pointing to the No1 plug tower and install distributor. You can use a timing lite to reset the timing.
YOU can if you have an engine scanner. if you have not fooled with the distributor then there is no need to adjust the timing because it is controlled by the ECM / computer. It will adjust it's self.
The 97 Chevy Suburban doesn't have a timing belt.
